The Pelican 1770 Long Case Black 54.5" Internal No Foam is a heavy-duty, oversized protective transport case engineered to safeguard extra-long firearms, precision instruments, and sensitive field gear. Supplied empty without interior foam, this configuration provides an open internal volume of 4.25 cu ft (0.12 m³) for bespoke bracketry, padded bags, or custom cutouts. Built from high-impact polypropylene with an EPDM O-ring seal, it delivers crushproof, dustproof, and watertight protection rated to IP67 ingress standards and MIL-STD-810G durability requirements.

Key Features

• Dual Purge Valves: Features twin integrated automatic pressure equalization purge valves that balance internal air pressure during altitude shifts while blocking water and dust ingress.
• Heavy-Load Mobility: Equipped with built-in wide-track polyurethane wheels with ball bearings/nylon hubs, two double-wide side handles for two-person lifting, and fold-down rubber overmolded handles.
• Secure Stacking: Molded base-to-lid locking cleats enable stable cross-stacking on pallets, in transport vehicles, or during storage.
• Reinforced Security: Features 0.31" (0.79 cm) stainless steel-reinforced padlock protectors paired with robust ABS double-throw latches tested to withstand up to 400 lbs of pull force.

Who is the Pelican 1770 Long Case Black 54.5" Internal No Foam for?

• ELR and precision long-range rifle shooters — Requires the 54.58" × 15.58" × 8.63" interior cavity of this oversized hard rifle case to accommodate full-length target systems with extended barrels, muzzle brakes, and tall mounted optics without disassembling the system.
• Anti-materiel rifle owners using .50 BMG platforms — Needs the substantial 280.00 lbs (127.01 kg) buoyancy rating and reinforced polypropylene shell of this hard case to safely float, transport, and protect heavy large-calibre weapon systems and spare magazines in transit.
• Tactical or industrial field teams — Relies on the -40°C to 87°C operating envelope and dual purge valves of this transport case to protect delicate survey drill assemblies, long optical rails, or multi-gun deployments through severe environmental changes.

Less suitable for: Standard hunting rifles under 50 inches where weight reduction is critical; a standard-length, lightweight single-rifle transport case (or lightweight slimline case) fits single-operator dismounted foot transport better than this 16.33 kg oversized case.
